2.1 Pre-installation
The Auteldac 4 telephone is connected by hard-wiring - (unlike a normal
plug and socket on internal telephones). Because of this, extra
precautions must be observed: installers must ensure that they have
the permission of the owner of the PABX or telephone network to which
the telephone is to be connected, and that installation is carried out by
trained personnel. Contact GAI-Tronics if installation service is required.
The symbol shown here and on the product means that the
product is classed as Electrical or Electronic Equipment and
should not be disposed with other household or commercial
waste at the end of its working life.
The Waste of Electrical and Electronic Equipment (WEEE)
Directive has been put in place to recycle products using best
available recovery and recycling techniques to minimise the
impact on the environment, treat any hazardous substances
and avoid the increasing landfill.

mounting.
IMPORTANT WARNING - Gland Specifications
Glands are not supplied. All glands and cables should comply with IP54
or better to meet ‘Increased Safety’ (‘e’ type) requirements. Only ‘e’ type
glands and suitable cables should be used and must be fitted correctly.
Note that the environmental rating of the telephone will not exceed that
of the glands, i.e. in order to maintain an IP66 rating, glands must also
meet IP66.
ALL POSSIBLE MEASURES MUST BE TAKEN TO ENSURE
WATER, FLUID OR DUST DOES NOT CONTAMINATE THE
INTERNAL COMPONENTS OF THE TELEPHONE WHILST
UNPACKING, PREPARING AND INSTALLING IT IN INCLEMENT
WEATHER CONDITIONS OR BY NEGLIGENCE.
FAILURE TO TAKE THIS PRECAUTION WILL INVALIDATE YOUR
WARRANTY AND CERTIFICATION
The telephone body must NOT be opened, nor glands removed or
cables disconnected unless all supplies to the telephone, including
telephone cables and external devices have been isolated outside the
hazardous area. Terminals for incoming cables are ‘e’ type and must be
carefully connected so as to make an ‘e’ type termination.
The Code of Practice for ‘e’ type enclosures is specified in EN60079-14.
The installer and all service personnel should be familiar with the
relevant sections of these documents.
If only one gland entry is used, the sealing plug fitted to the second
gland position should be left in place.
2.2 Protection Against Hazards
The Auteldac 4 telephone has been designed such that it does:-
-Not give rise to Physical injury or harm due to contact.
-Not produce excessive surface temperature, infra-red,
electromagnetic or ionising radiation.

2.2.1 IMPORTANT WARNING:- Risk of Tripping or entanglement
For Auteldac 4 telephone versions supplied with long corded handset &
headsets
Telephone location:-
Care must be taken when installing the telephone onto a wall, post or
flat surface, to position the telephone so that the lower extremities of
the stowed handset/headset cord do not pose an entanglement or
tripping hazard.
Use of telephone:-
Some of the long corded (headset & handset) versions of the telephone
can reach to over 5 metres away from the telephone position. Therefore
caution and care must be taken when using the handset/headset at
these extended distances, so that the user and other personnel or
equipment in the vicinity is not impeded, trapped or entangled by the
cord. Also, care must be taken to stow these long cord
handset/headsets so they do not pose an entanglement or tripping
hazard.
2.2.2 IMPORTANT WARNING: Ringer high noise level hazard:-
The telephone ringer can develop a sound level in excess of 90dBA @
1 metre. Therefore, it is the installer’s responsibility to take the
necessary measure to comply with the European directive 2003/10/ec
on the minimum health and safety requirements regarding the exposure
of workers to the risks arising from physical agents (noise).
2.3 Preparation
1. Place the telephone on its base on a firm horizontal surface.
2. Using a 5mm Allen key, release the Front Casing from the Rear
Casing. The screws are captive in the Front Casing.
3. Noting the positions, disconnect the keypad cable at the keypad.
See figure 8, on Page 18.
4. Take care when removing the Front Casing from the Rear Casing
and storing the Front Casing not to damage the internal electronics,
specifically the headset switch terminals or connector PCB if fitted.
To do so will violate the certification of the telephone product.
5. Remove the RED blanking plug from the cable entry hole leaving the
EEx e certified (usually BLACK) blanking plug in situ.
NOTE: The EEx e plug must be used to seal the unused gland
hole; failure to do so will invalidate the certification of the
telephone product.

2.6 Desk Mounting / Rake
IMPORTANT WARNING:- Risk of impact or falling
This telephone, when used in a desk mounting mode, should be located
on a horizontal, flat non-slip surface. Due to the heavy and robust
construction of the unit, users must take care when using the handset
or headset, not to pull the cord to such an extent as to cause the
telephone to be pulled off the flat surface, and possibly cause damage
or injury to persons or equipment. Therefore it is recommended that the
unit be fixed in position using fixing positions and method detailed in
section 2.4 if there is any risk of the unit being dislodged as described
above.
To provide a 'rake' for convenient operation, the Front Casing may be
turned through 180°before it is fitted to the Rear Casing. Thus the
cable entries are at the rear of the telephone.
1. Ensure that the supplied rubber feet are fitted to the underside of the
Rear Casing if the telephone if not fixed into position.
2. Rotate the Front Casing through180°and fold the keypad ribbon
cable to ensure that it lays flat against the potted block when re-

Maximum voltage = 240Vrms
Maximum current = 5A
Note: no fusing or transient protection is provided; this must be
installed externally.
Note: The minimum ring voltage required to operate the ring relay
depends on the frequency of the ring signal and on the loudness
setting of the Auteldac 4 ringer. Approximate minimum values (in V
rms) are shown in the table below:
Ring frequency (Hz)
Volume setting 50Hz 25Hz
Quiet 35 39
Medium 36.5 40
Loud 39 46
V. Loud 54.5 62
The ring detect relay fitted to the Auteldac 4 has a continuous
current rating of 5A. It has been brought to our attention that some
beacons, whilst having a current rating well below this figure,
actually generate current spikes far in excess of this during making
and breaking of the relay contacts. These current spikes can cause
the relay contacts to fail.
GAI-Tronics have been working closely with a leading beacon
manufacturer to resolve this issue and our recommendations are:
•Restrict the use of beacons to non AC variants only or those
with a maximum flash intensity of 5 joules.
•Where beacons with greater than 5 joule flash intensity are
required, the beacons should be purchased directly from GAI-
Tronics, who will ensure compatibility with the Auteldac 4 and
that ATEX approvals are not compromised.
•Utilise only beacons with integral ring detector, so that the relay
in the Auteldac 4 is not needed to activate the beacon.
2.7.3 Hook Switch State Indicator Contact
(Optically isolated, volt-free contact)
The connection from the telephone to the hook switch state indicator
must be installed such that the apparatus continues to comply with
